The article doesn't mention how or what kind of location data will be collected/used. There is no explicit mention of tracking location using smartphones or laptops.

It is mentioned that the firm already uses location data in connection with billable hours (verifying/approving the billable hours, I'm guessing). Again, no mention of how/what location data is collected.

It is mentioned that EY does something similar (office attendance tracking) using swipe card data.

Yeah it’ll just be swipe cards. You can’t really move around offices like these without swiping through doors regularly
